A METHOD OF PRODUCING A MIXING PACKAGE EMPLOYING TWO SEPARATE CQNTAINERS I F'lled June 24, 1968 from/145% 3,548,562 METHOD OF PRODUCING A MIXING PACKAGE EMPLOYING TWO SEPARATE CONTAINERS Gilbert Schwartzman, 20 Wilmot Circle, Scarsdale, NY. 10583 Filed June 24, 1968, Ser. No. 739,253 Int. Cl. B65d 85/00; B65b 63/08 US. C]. 5325 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to a mixture package, employing two separate containers and has for its primary object the provision of a mixing package assembly adapted to facilitate the separate shelf storage of two substances to be thereafter mixed.

The present invention is especially adapted for utilization for use with two materials or substances which have an extended shelf life when not mixed, but which must be utilized relatively soon after mixture to prevent deterioration. Various cosmetics, medications, hair dyes, pigments, polishes, cleaning solutions and the like havethe foregoing characteristics. For example, conventional hair dyes employ a base material such as a peroxide solution or the like, with which a pigmented material or solution is mixed for immediate application on the hair. The color is determined by the make-up of the pigmented solution. If the pigmented material is mixed with the base and allowed to stand, the mixture deteriorates and becomes unusable. It is often very messy to mix these solutions together using separate containers, and the present invention overcomes these difliculties and provides a unitary storage and mixing facility.

Another object of the invention resides in the provision of a mixing package that permits the separate shelf storage of two substances of an unstable mixture and which facilitates the mixture of the two substances of all without removing the substances from the simple assembly comprising the present invention or requiring any exterior handling thereof.

The construction of this invention features the use of two separate containers, at least one of which is flexible and carries puncturing rods. A frangible seal is disposed betwene the containers and a threaded collar is used to hold the assembly together.

Still further objects and features of this invention reside in the provision of a mixing package which is simple and inexpensive to manufacture, easy to use, and which is especially adapted for use in connection with cosmetics, medications, hair dyes and tints, polishes, and the like.

These, together with the various ancillary objects and features of the invention which will'become apparent as the following description proceeds, are attained by this dauber, a preferred embodiment of which has been illustrated in the accompanying drawing, by way of example only, wherein:

FIG. 1 is a vertical sectional detail view of an assembled mixing package constructed in accordance with the concepts of the present invention;

FIG. 2 is a cross-sectional view similar to FIG. 1, but illustrating the invention after opening.

United States Patent Ofice 3,548,562 Patented Dec. 22, 1970 FIG. 3 is a transverse sectional view taken along the plane of line 3-3 in FIG. 1;

FIG. 4 is a vertical sectional view of a modified form of one container used in the invention; and,

FIG. 5 is a partial sectional detail view illustrating how one of the containers is filled.

With continuing reference to the accompanying drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral is used to generally designate a mixing package constructed in accordance with the concepts of the present invention. The mixing package includes four main elements, a first container 12, a second container 14, a frangible seal 16, and a locking collar 18.

The container 12 is adapted to be constructed out of any readily available material such as glass or plastic and is provided with external threads in the upper end thereof. The uppermost end of the container 12 forms a shoulder 22. The container 14 has an open lower end defined by a peripheral flange 24 and is provided with an upwardly substantial truncated conical shape side wall 26 and is provided an integrally formed top 28. The top is provided with a neck 30 which is externally threaded at 32 and provided with an opening therein 34 into which material may be poured or from which material may be dispensed.

The container 14 is molded out of any suitable synthetic plastic material, such as polyurethane, which is flexible and preferably resilient and which has integrally formed therewith and depending therefrom a pair of rods 36, each of which terminates in a pointed end 38. The rods 30 are disposed on either side of the neck 30 and extend downwardly to a point immediately adjacent to the plane of the flange 24 and of the seal 16. A threaded cap is provided with internal threads for thread engagement on the neck 30 and has an integral plug 42 for extending into the opening 34.

The locking collar 18 is provided with threads 44 for threaded engagement with the threads 20 and has a peripheral downwardly extending flange 46 which is adapted to engage the flange 24 so as to hold the assembly together.

A first material such as a fluid or powdered material 48 is disposed in the container 12. Then the frangible seal 16 which is very thin and easily pierced by the piercing rods 36 is disposed on the shoulder 22. Thereafter, in an inverted position the container 14 is disposed with the flange overlying the seal and resting on the container 12. Then, the threaded collar 18 is screwed down clampingly holding the entire assembly in place after which material may be dispensed through a funnel 50 (see FIG. 5) into the opening 32 to fill the opening 34 with a second material, either a liquid or a powder-like material as indicated at 52, after which the cap 40 can be inserted on the neck 30 to seal the container keeping the two materials 48 and 52 entirely separate. When it is desired to use the materials in a mixed condition, the cap is depressed downwardly, as indicated by arrow 54, causing the resilient flexible walls 26 of the container 14 to flex and permitting the pointed ends 38 which were immediately adjacent the seal 16 to penetrate the seal and allow the material 52 to fall downwardly in the direction indicated by arrows 56. After the two materials have been mixed, by removing the cap 40, the two materials can be dispensed.

Referring to FIG. 4 it will be seen herein that in lieu of the neck 30 a spout can be employed which has a snapable end 62. When it is desired to utilize the container of the form shown in FIG. 14, this can be accomplished by placing a material such as a liquid 68 therein and freezing it in place at which time the material will bond to the container 14 and to the rods 36' with the rods 36' serving to hold the frozen material 68 in place. Then the container 14 may be turned upside down and placed on the seal 16, in the same manner as the container 14 was placed on the seal 16, after which the locking collar 18 can be used to clampingly hold the assembly together. Thereafter, the material 68 is allowed to thaw and the package is ready for an extended shelf life. Depression of the container 14' after thawing of the material 68 will cause rupturing of the seal and allow the material to mix after which the end 62 of the spout can be snipped or snapped off and material dispensed from the spout.

A latitude of modification, substitution and change is intended in the foregoing disclosure, and in some instances, some features of the invention will be employed without a corresponding use of other features.

I claim:

1. A method of packaging for future mixing of two materials comprising the steps of filling a first container with a first material, positioning a frangible seal thereover, filling a second container having means for breaking said frangible seal with a second material in liquid state, freezing said second material to a solid state, with said means for breaking said frangible seal aiding in holding said second material in position in said second container, then overturning said second container and disposing said second container on said seal, thereafter securing said second container to said first container, and allowing said second material to thaw back to a liquid state.
